The Philly Cheesesteak Casserole originated from the iconic Philadelphia Cheesesteak sandwich, which has been a beloved staple in the city since the 1930s. As cooks sought new ways to enjoy this savory classic, the idea of a casserole emerged, merging convenience with comfort food.
In the late 20th century, home cooks began experimenting with layering steak, cheese, and vegetables in a baking dish, creating a hearty, one-pan meal. This adaptation quickly gained popularity, especially among families seeking to simplify their dinner preparations while still savoring the flavors of the original sandwich.
Over time, the casserole became a favorite in potlucks and gatherings, showcasing its versatility and ability to feed a crowd. Today, Philly Cheesesteak Casserole stands as a testament to culinary creativity, bridging tradition with modern convenience.
Philly Cheesesteak Casserole
INGREDIENTS
- 1 lb thinly sliced beef (steak, sirloin, or roast beef)
- 2 tablespoons olive oil (or butter)
- 1 medium onion, thinly sliced
- 1 medium green bell pepper, thinly sliced
- 1 medium red bell pepper, thinly sliced
- 3 cloves garlic, minced
- 1 cup mushrooms, sliced (optional)
INSTRUCTIONS
Preheat your oven to 350°F (175°C).
In a large skillet over medium heat, add the olive oil (or butter). Once hot, add the sliced onions and cook until they start to soften, about 3-5 minutes.
Add the sliced green and red bell peppers, and mushrooms if using, to the skillet. Cook for an additional 5-7 minutes until vegetables are tender.
Stir in minced garlic, salt, black pepper, Worcestershire sauce, and oregano. Cook for an additional 1-2 minutes until fragrant.
Increase the heat to medium-high and add the thinly sliced beef to the skillet. Cook until the beef is browned and cooked through, about 5-7 minutes.
In a large mixing bowl, combine the cubed hoagie rolls with the beef and vegetable mixture. Stir in the beef broth and mix until everything is evenly coated.
Transfer the mixture to a greased 9×13-inch baking dish. Top with provolone and mozzarella cheese, spreading it evenly across the top.
Cover the baking dish with aluminum foil and bake for 25 minutes.
After 25 minutes, remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden brown.
Remove from the oven, let it cool for a few minutes, and serve.
